Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy

IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

Long-Standing Ulcerative Colitis May Trigger a Multilineage Cancerization Field

Longstanding/relapsing inflammation characterizing ulcerative colitis (UC) has been associated to an increased risk of colon mucosa neoplastic transformation. We describe the clinicopathological features of a UC-related poorly-differentiated neuroendocrine carcinoma coexisting with a conventional adenocarcinoma. This case supports UC as a multilineage cancerization field. </jats:p

Giant condyloma acuminatum of the anorectum (Buschke-lowenstein tumour): a case report of conservative surgery

Giant condyloma acuminatum of the anorectum (Buschke-Lowenstein tumour) is a rare interesting infectious disease caused by the papillomavirus serotypes 16 and 18. In January 2002 a 47-year-old heterosexual male presented with Buschke-Lowenstein tumour and reported having had the disease for 12 years. The patient underwent thorough screening for sexually-transmitted diseases (which proved negative), abdominal CT, transanal US-endoscopy, inguinal ultrasound, chest X-ray and anorectal manometry, which revealed only localized disease. He was treated conservatively with radical local excision of the lesions. No postoperative complications were observed. Twelve months after surgery, there has been no local or remote recurrence and faecal continence is normal. The treatment of choice for Buschke-Lowenstein tumour is controversial; there is no evidence to support the need for demolitive surgery or chemo- and/or radiotherapy. The majority of authors prefer abdominoperineal amputation, but in our opinion conservative surgery is the best choice, especially in terms of the patient's quality of life

Immediate and long term complications of prolonged-venous-access devices (PVAD): a comparison between surgical cutdown and percutaneous techniques.

There is currently still no consensus regarding the best technique for implanting prolonged-venous-access devices (PVAD). One hundred ninety-six patients underwent surgical PVAD positioning using an all-surgical cutdown approach to the cephalic vein (CV). When surgical cannulation proved impossible, the patient was converted to percutaneous positioning. A retrospective analysis was performed on the difference between these two techniques. Among the 196 patients who underwent the surgical insertion of a PVAD, 23 (11.7%) were converted to percutaneous cannulation. For the surgical cannulation group, the median operating time was 35 minutes vs the 52.5 minutes needed for the percutaneous cannulation group. The median time of fluoroscopy amounted to eight seconds for the surgical cannulation group vs 18 seconds for the percutaneous cannulation group. Complications were observed in 23/196 patients (11.7%): 9/23 patients (39.1%) developed infections. Deep venous thrombosis was observed in 4/23 patients (17.4%). Pneumothorax and arterial hematoma developed in 5/23 patients (21.7%), all cases of percutaneous placement. PVAD malfunction was observed in 3/23 patients (13.0%). We concluded that surgical cutdown is faster than the percutaneous approach and safer for both patient and surgeon, involving a shorter time of exposure to radiation and reducing the risk of infection. --------------------------------------------------------------------------------

Carotid endarterectomy in women: Early and long-term results.

Background. Although many randomized trials and other multicenter studies have demonstrated the benefits of carotid endarterectomy (CEA) in selected symptomatic and asymptomatic patients, including women, there is a remarkable lack of reports regarding the outcome of CEA with respect to sex. To analyze and compare the outcome of CEA in men and women in a single-group experience, we reviewed a consecutive series of 619 CEAs performed in 539 patients, 371 men (423 CEAs) and 168 women (196 CEAs). Methods. Data collection was retrospective up to August 1, 1992 and prospective for all 405 patients treated thereafter. Results. Women were significantly less likely than men to have overt evidence of coronary artery disease (P < .001) and had a significantly higher incidence of diabetes (P < .001). No perioperative death occurred in the female group (P = NS), and no statistical difference was found in perioperative stroke risk incidence. Women had a significantly higher incidence of late occlusive events (P = .01), which were all asymptomatic. No late stroke occurred in the female group (P = NS). Life-table cumulative survival rates at 1, 3, 5, and 7 years were 99.3%, 90.5%, 85.9%, and 82.3%, respectively, in women, and 98.9%, 91.9%, 85.2%, and 79.6% in men (log-rank P = .8). Conclusions. These findings show that perioperative stroke risk and mortality rates, as well as late strokefree, mortality, and recurrence rates, in patients undergoing CEA, are comparable in men and women. Further, larger comparative studies are necessary to provide more information on the benefit and durability of CEA in asymptomatic patients, but the results of this study suggest that the early and late outcomes are excellent and comparable in symptomatic and asymptomatic men and women
